Frost Risk Probability

Based on 21 years of NOAA weather station data from 2 stations

Too early frost risk Safe to Plant Jan 15 → Dec 10 330 frost-free days Protect crops frost returns Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Safe: Feb 9 Protect by: Dec 21

Beginners: Plant frost-sensitive crops (tomatoes, peppers, squash) after the "Safe" date on the left. Harvest or cover them before the "Protect by" date on the right. Hardy crops (lettuce, peas, kale) can go in the yellow transition zones.

How to read this table: "Conservative" means you're safe from frost 9 out of 10 years — best for beginners and frost-sensitive crops. "Average year" is the typical date. "Aggressive" means only 1 in 10 years is that warm — experienced gardeners with frost protection can try these dates.

Planting Strategy Last Spring Frost First Fall Frost Frost-Free Days
Conservative (safest) Feb 9 Dec 21 315 days
Cautious Jan 23 Dec 17 328 days

Organic pest management tips
  • Use row covers on susceptible crops during peak pest months
  • Apply neem oil preventatively every 7-14 days during active pest season
  • Interplant with strong-scented herbs (basil, marigold) to confuse pests
  • Hand-pick larger pests (beetles, caterpillars) in early morning when they're sluggish
  • Practice crop rotation — never plant the same family in the same spot within 3 years

Wind & Microclimate

Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.

Seasonal Wind Speed

Spring: 12 mph   Summer: 12 mph

Fall: 9 mph   Winter: 10 mph

Prevailing wind: W. Moderate wind — consider a temporary windbreak for young seedlings.

Windbreak Benefit

4.8/10

Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.

Frost Pocket Risk

Low

Relatively flat terrain (327 ft range). Frost pocket risk is minimal — garden placement is flexible.

Rainwater Harvesting Potential

How much water you can collect, when to collect it, and what size system you need for your garden.

8 rain barrels (55 gal each)

For a typical 500 sq ft garden. Serious collectors: consider a 2,500 gal tank.

Legal Status

Unrestricted

Rainwater harvesting is fully legal in your state with no restrictions.

Best Collection Months

Jan, Feb, Mar, Dec

Highest rainfall months — your barrels will fill up quickly during these months.

Months to Draw From Storage

May, Jun, Jul, Aug, Sep, Oct

Dry months when you'll rely on stored water — size your storage for this gap.

Rainwater collection tips for your area
  • Your county receives approximately 16.4 inches of rain per year
  • A 1,000 sq ft roof can collect roughly 8,173 gallons annually
